Hi all,..
wired mBed up to an SE95 temp sensor.
set the RTC, and have it logging to the filesystem.
I get this nice graph, but as you can see 3x Brand New AA's last about 4.5 hours.
second time I've tried it, 4xAA's don't last much longer.
so, is this what you'd expect ? If it's right, then it's right.. I just want to know if that's normal, and what's the best way to power it away from my PC.
(this was out in my shed this afternoon, I was hoping to leave it overnight!)
cheers
Dave.
